Abstract

A method and apparatus for multi-coprocessor load balancing. The method comprises: a main processor obtaining the traffic weight of each virtual interface to be allocated (11); the main processor obtaining the total traffic weight value on each virtual interface, wherein the total traffic weight value on the coprocessor is the sum of the traffic weights of all the virtual interfaces allocated on the coprocessor (12); and the main processor orderly allocating the large-traffic-weight virtual interfaces to be located to the coprocessors with small total traffic weight value (13). Each virtual interface correspondingly has the traffic weight of the respective traffic, and when the coprocessors are allocated for the virtual interfaces, the balance of the total traffic weight values corresponding to the various coprocessors is kept, so that traffic processed correspondingly by the various coprocessors become balanced. Compared with the methods in which allocation is performed simply based on the number of the virtual interfaces of the coprocessors, the method brings a more significant load balancing effect.

Description

一种多协处理器负载均衡的方法、装置及主处理器Method, device and main processor for multi-coprocessor load balancing 技术领域Technical field
本发明涉及IPSec(Internet协议安全性)领域，特别是一种实现多协处理器负载均衡的方法、装置及主处理器。The invention relates to the field of IPSec (Internet Protocol Security), in particular to a method, a device and a main processor for implementing multi-coprocessor load balancing.
背景技术Background technique
IPSec是一种开放标准的框架结构，通过使用加密的安全服务以确保在Internet协议网络上进行保密而安全的通讯。IPsec定义了在网际层使用的安全服务，其功能包括数据加密、对网络单元的访问控制、数据源地址验证、数据完整性检查和防止重放攻击。IPSec is an open standard framework that ensures secure and secure communications over Internet Protocol networks by using encrypted security services. IPsec defines the security services used at the Internet layer, and its functions include data encryption, access control to network elements, data source address verification, data integrity checking, and replay prevention attacks.
由于IPSec处理流程复杂，实时要求性高，对设备处理能力提出较高的要求。单个主处理器(main processor，MP)的处理能力有限，而且设备通常不仅仅处理IPSec报文，还需要承担其他功能，因此需要配置多个协处理器(coprocessor，CP)专门进行IPSec报文处理。Due to the complexity of the IPSec processing process and the high real-time requirements, high requirements are placed on the processing capability of the device. A single main processor (MP) has limited processing capacity, and the device usually needs to handle not only IPSec packets but also other functions. Therefore, multiple coprocessors (CPs) need to be configured for IPSec packet processing. .
当存在多个协处理器时，为协处理器分配虚接口则需要保证负载均衡。目前保证协处理器负载均衡的方法是按照协处理器的虚接口数量来进行均衡分配的。由于不同虚接口所对应的流量大小不同，因此，采用上述现有的分配方法并不能真正意义上的实现协处理器的流量均衡。When there are multiple coprocessors, assigning a virtual interface to the coprocessor requires load balancing. Currently, the method of guaranteeing coprocessor load balancing is balanced according to the number of virtual interfaces of the coprocessor. Since the traffic sizes corresponding to different virtual interfaces are different, the above-mentioned existing allocation method does not truly achieve the traffic balance of the coprocessor.

下面结合实施例对步骤131-步骤133进行详细介绍。Steps 131 to 133 are described in detail below in conjunction with the embodiments.
<实施例一><Example 1>
示例性地，在本实施例一中，假设有3个未配置有协处理器的虚接口，即虚接口1-3，其对应的流量权重分别是5，8，4。某一设备共有3个协处理器，即当前流量权重总值为10的协处理器1、流量权重总值为8的协处理器2以及流量权重总值为13的协处理器3。Illustratively, in the first embodiment, it is assumed that there are three virtual interfaces that are not configured with a coprocessor, that is, virtual interfaces 1-3, and the corresponding traffic weights are 5, 8, and 4, respectively. A device has three coprocessors, namely, a coprocessor with a total traffic weight of 10, a coprocessor 2 with a total traffic weight of 8, and a coprocessor 3 with a total traffic weight of 13.
在配置虚接口时，对协处理器按照流量权重总值的大小进行升序排列，即协处理器的排列次序为表一所示：When configuring a virtual interface, the coprocessors are sorted in ascending order according to the total value of the traffic weights, that is, the order of the coprocessors is as shown in Table 1:
排列次序Sort order 协处理器编号Coprocessor number 流量权重总值Total flow weight
11 协处理器2Coprocessor 2 88
22 协处理器1Coprocessor 1 1010
33 协处理器3Coprocessor 3 1313
表一Table I
之后根据流量权重的大小，对未配置有协处理器的虚接口进行降序排列，其排列次序如表二所示：Then, according to the size of the traffic weight, the virtual interfaces that are not configured with the coprocessor are arranged in descending order. The order of the virtual interfaces is as shown in Table 2:
排列次序Sort order 虚接口编号Virtual interface number 流量权重Flow weight
11 虚接口2Virtual interface 2 88
22 虚接口1Virtual interface 1 55
33 虚接口3Virtual interface 3 44
表二Table II
按照排列次序从表二中选取虚接口2、1、3。之后将虚接口2分配至表一中排列次序第一的协处理器2，将虚接口1分配至表一中排列次序第二的协处理器1，以及虚接口3分配至表一中排列次序第三的协处理器3。The virtual interfaces 2, 1, and 3 are selected from Table 2 in the order of arrangement. The virtual interface 2 is then assigned to the coprocessor 2 in the first order in Table 1, the virtual interface 1 is assigned to the coprocessor 1 in the second order in Table 1, and the virtual interface 3 is assigned to the order in Table 1. The third coprocessor 3.
在虚接口1、2、3全部配置完成后，协处理器1对应的流量权重总值为15，协处理器2对应的流量权重总值为16，协处理器3对应的流量权重总值 为17。由于流量权重总值即代表着协处理器对应的所有虚接口的流量总大小，因此在配置结束后，协处理器在流量上实现了负载均衡。After all the virtual interfaces 1, 2, and 3 are configured, the total traffic weight corresponding to coprocessor 1 is 15, the total traffic weight corresponding to coprocessor 2 is 16, and the total traffic weight corresponding to coprocessor 3. Is 17. Since the total traffic weight value represents the total traffic size of all virtual interfaces corresponding to the coprocessor, the coprocessor implements load balancing on the traffic after the configuration ends.
此外，可在分配虚接口时，可动态更新协处理器的排列顺序，下面介绍一个可行的实现方式。In addition, the order of coprocessors can be dynamically updated when the virtual interface is allocated. A possible implementation is described below.
在上述基础上，所述待分配的虚接口为X个，协处理器为Y个；On the basis of the above, the virtual interfaces to be allocated are X, and the coprocessors are Y;
当X大于Y时，在执行上述步骤133时，主处理器在分配完第Y个待分配的虚接口后，根据流量权重总值的大小对所有协处理器重新进行升序排列；之后根据待分配的虚接口的排列顺序，以及协处理器新的排列顺序，将流量权重大的剩余待分配的虚接口分配给流量权重总值小的协处理器。When X is greater than Y, when performing the above step 133, after all the Y virtual interfaces to be allocated are allocated, the main processor re-arranges all the co-processors according to the total value of the traffic weights; The order of the virtual interfaces and the new order of the coprocessors are allocated to the remaining virtual interfaces to be allocated with a large traffic weight to the coprocessor with a small total flow weight.
下面以一个实施例对上述方案进行详细介绍。The above scheme will be described in detail below with an embodiment.
<实施例二><Embodiment 2>
示例性地，在本实施例二中，假设有6个未配置有协处理器的虚接口，即虚接口1-6，其对应的流量权重分别是1，3，5，7，13，16。某一设备共有3个协处理器，即当前流量权重总值为31的协处理器1、流量权重总值为32的协处理器2以及流量权重总值为33的协处理器3。Illustratively, in the second embodiment, it is assumed that there are six virtual interfaces that are not configured with a coprocessor, that is, virtual interfaces 1-6, and the corresponding traffic weights are 1, 3, 5, 7, 13, 16 respectively. . A device has three coprocessors, namely, a coprocessor with a total traffic weight of 31, a coprocessor 2 with a total traffic weight of 32, and a coprocessor 3 with a total traffic weight of 33.
在配置虚接口时，对协处理器按照流量权重总值的大小进行升序排列，即协处理器的排列次序如表三所示：When configuring a virtual interface, the coprocessors are sorted in ascending order according to the total value of the traffic weights, that is, the order of the coprocessors is as shown in Table 3:
排列次序Sort order 协处理器编号Coprocessor number 流量权重总值Total flow weight
11 协处理器1Coprocessor 1 3131
22 协处理器2Coprocessor 2 3232
33 协处理器3Coprocessor 3 3333
表三Table 3
之后根据流量权重的大小，对未配置有协处理器的虚接口进行降序排列，其排列次序如表四所示：Then, according to the size of the traffic weight, the virtual interfaces that are not configured with the coprocessor are arranged in descending order, and the order of the virtual interfaces is as shown in Table 4:
排列次序Sort order 虚接口编号Virtual interface number 流量权重Flow weight
11 虚接口6Virtual interface 6 1616
22 虚接口5Virtual interface 5 1313
33 虚接口4Virtual interface 4 77
44 虚接口3Virtual interface 3 55
55 虚接口2Virtual interface 2 33
66 虚接口1Virtual interface 1 11
表四Table 4
由于总共有3个协处理器，因此从表二中选取排列次序前3个的虚接口6、5、4。之后将虚接口6分配至表一中排列次序第一的协处理器1，将虚接口5分配至表一中排列次序第一的协处理器2，以及虚接口4分配至表一中排列次序第一的协处理器3。Since there are a total of three coprocessors, the first three virtual interfaces 6, 5, and 4 of the order are selected from Table 2. The virtual interface 6 is then assigned to the coprocessor 1 in the first order in Table 1, the virtual interface 5 is assigned to the coprocessor 2 in the first order in Table 1, and the virtual interface 4 is assigned to the order in Table 1. The first coprocessor 3.
之后重新根据流量权重总值的大小对协处理器进行升序排列，对应的更新后的表三如下所示：Then, the coprocessors are reordered according to the total value of the traffic weights, and the corresponding updated table 3 is as follows:
排列次序Sort order 协处理器编号Coprocessor number 流量权重总值Total flow weight
11 协处理器3Coprocessor 3 4040
22 协处理器2Coprocessor 2 4545
33 协处理器1Coprocessor 1 4747
更新后的表三Updated Table 3
从表二中按照排列次序选取余下的3个虚接口，即虚接口3、2、1。将虚接口3分配至更新后的表三中排列次序第一的协处理器3，将虚接口2分配至更新后的表三中排列次序第二的协处理器2，以及将虚接口1分配至更新后的表三中排列次序第三的协处理器1。From Table 2, the remaining three virtual interfaces are selected in order of arrangement, namely virtual interfaces 3, 2, and 1. The virtual interface 3 is allocated to the coprocessor 3 of the first order in the updated table three, the virtual interface 2 is assigned to the coprocessor 2 of the second order in the updated table three, and the virtual interface 1 is allocated. The third coprocessor 1 is arranged in the updated table three.
在虚接口1-6全部配置完成后，协处理器1对应的流量权重总值为48，协处理器2对应的流量权重总值为48，协处理器3对应的流量权重总值为45。可见，按照本实施例的配置方案，协处理1、2、3的流量权重总值趋近于均衡，由于流量权重总值即代表着协处理器对应的所有虚接口的流量总大小，因此在配置结束后，协处理器在流量上实现了负载均衡。After all the configurations of the virtual interface 1-6 are completed, the total traffic weight corresponding to the coprocessor 1 is 48, the total traffic weight corresponding to the coprocessor 2 is 48, and the total traffic weight corresponding to the coprocessor 3 is 45. It can be seen that, according to the configuration scheme of the embodiment, the total traffic weight of the co-processing 1, 2, and 3 approaches the equalization, and the total traffic weight represents the total traffic size of all virtual interfaces corresponding to the coprocessor, so After the configuration is complete, the coprocessor implements load balancing on the traffic.
需要说明的，上述实施例二仅仅是一种可行的实现方案，本发明的方法也可每分配一个虚接口就重新对协处理器进行升序排列。 It should be noted that the foregoing embodiment 2 is only a feasible implementation, and the method of the present invention may reorder the coprocessors every time a virtual interface is allocated.
综上所述，本实施例的方法在为虚接口分配协处理器时，真正在流量上实现了负载均衡。In summary, the method in this embodiment implements load balancing on the traffic when the coprocessor is allocated for the virtual interface.
